A Template Application for Running Axis2 in OSGi Environments

I'm using your axis2-osgi-example.zip. Great job!! But I have some problems I am doing some tests with the simple.version sample service and Calculator class. My new Calculator class is

public class Calculator {
public double add(double x, double y) {
return x + y;
}
public String hello (String nombre){
return "Hello " + nombre;
}
public Prueba getTabla(Prueba prueba){
System.out.println ("ENTRO EN WS GETTABLA " + prueba.getAttribute1()+
prueba.getAttribute2());
return prueba;
}
}

As you can see it is very simple. I have developed a client from generated wsdl file (myCal.wsld) using WSLD2Java. My client is invoking to add and hello methods correctly. My problem is the getTabla method. This receives a parameter from Prueba class. This class contains two attributes of type String (very simple). I can invoke to this method and the web service is receiving this call correctly. My problem is that the client can not understand the response from web service. This method returns the same parameter that it is receiving. This is the trace

Caused by: org.apache.axis2.AxisFault: org.apache.axis2.databinding.ADBException: Unsupported type null com.ws20.test.Prueba at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430) at com.ws20.test.MyCalStub.fromOM(MyCalStub.java:1015) at com.ws20.test.MyCalStub.getTabla(MyCalStub.java:640) at com.ws20.test.Activator.start(Activator.java:40) at org.eclipse.osgi.framework.internal.core.BundleContextImpl$2.run(BundleContextImpl.java:1009) at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.startActivator(BundleContextImpl.java:1003)

I can not complete the cycle.
1) Client sends a Prueba object
2) Server receives Prueba object
3 )Servers sends the same Prueba object
4) Client doesn´t understand the same object that was sent itself

I am debugging my Stub class and I have found the error but I can not understand why it isn't working if I am using generated code by WSDL2Java tool. Problem is in the parse method from Prueba class. I received this message to be parsed in the client.

ns:getTablaResponse xmlns:ns="http://test.ws20.com">
return xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="com.ws20.test.Prueba">
attribute1>paco attribute2>chensacion
/return>
/ns:getTablaResponse>

But this code is not working. As you can see there is a comparison between "Prueba" and type, but type is "com.ws20.test.Prueba". I mean class name + package name. This comparison is negative therefore fails in the code inside if sentence.

if (!"Prueba".equals(type)) {
//find namespace for the prefix
java.lang.String nsUri = reader.getNamespaceContext()
.getNamespaceURI(nsPrefix);
return (Prueba) ExtensionMapper.getTypeObject(nsUri, type, reader);
}

I can fix this using
if (!"com.ws20.test.Prueba".equals(type)) {
//find namespace for the prefix
java.lang.String nsUri = reader.getNamespaceContext() .getNamespaceURI(nsPrefix);
return (Prueba) ExtensionMapper.getTypeObject(nsUri, type, reader);
}

and that is working correctly. But I can not understand why this code can be wrong. I mean it is code from WDSL2Java, it haven´t developed by me. Maybe I need a wsdd file but I don´t know how it is possible pass it when you register Calculator as Osgi service with WSTracker.Axis2_WS property

Could you help me? I am very interested in Axis2 and Osgi. I need this kind of technology. Thanks in advanced

If you mean by integrating with OSGi as the same ideas, yes, I think every project has such ideas, but the actual problem is implementing them ;)

 

great,

Currently there is ongoing work in the Axis2 project to make Axis2 engine not only compatible with OSGi but also take all the advantages that OSGi infrastructure provides so developers could deploy Web Services and Modules in bundles.

The starting point to achieve this is by instrumenting an OSGi implementation and providing means to monitor and manage it accordingly to business and environmental requirements. thanks, free online storage

i followed your instructions, but i miss the javax.servlet package. all other packages were generated without any problem, but javax.servlet isn't there and the pom.xml entry for it is missing, too.
